Roofing damage can sometimes be caused by heavy snowfall. While this isn’t always the case, there are factors that can lead to it, and they usually have to do with the structural integrity of your roof as well as its ability to keep a balanced set of conditions inside your home and in your attic.
Attic ventilation is the main issue here. In most cases, poor ventilation can cause your home to either heat up too much or lose too much heat. The unbalance between the heat in your home and the cold outside, as well as the condensation caused by it, can lead to the snow melting during the day and then freezing and causing ice dams to form near the edge of your roofing structure during the night.
As precipitation increases, and more snow falls, the added weight as the snow is held on top of your roof by the ice dams, will cause the roof to be under extreme strain, and sometimes the weaker points may even collapse under the added weight.
This is mainly the mechanism through which heavy snowfall can and will damage your roof. To make sure you can prevent it or to do some damage control once it’s already happened, make sure to contact your local Junction City roofing contractors and ask for advice.
